System description of the hybrid guideway The base for the maglev guideway design is the specification of the system industry. For the Transrapid, they are as follows: • Very high stiffness, both vertically and horizontally (max fz < L/4.800; max fy < L/18.000) • Strong against deformation or rather non deformable • Clear away all stimulations by the maglev vehicle • Compliance with the system’s high tolerance requirements in the functional elements of the guideway Since tolerances of only less than a tenth of a millimeter cannot be realized in the conventional reinforced concrete or...

System description of the concrete guideway Connecting parts, the so called consoles and the functional modules of the hybrid guideway are made of steel. This design, however, represents costs of approximately 60  % of the hybrid guideway, which still leaves plenty of space for economic optimization – regards fabrication as well as maintenance and inspection costs. Therefore steel parts of the hybrid guideway beam which are not mandatory for the operation of the maglev vehicle, were reduced and replaced by concrete. Approximately 75  % of the steel weight was saved. The production costs...

System cross sections MGB Type I – 24,8 m The type I girder is optimized with its closed box crosssection to the structural needs, the requirements regarding the trackway evenness as well as production process. The girder is manufactured with fixed bearing pedestal and can be equipped with all maglev guideway innovations of the Max Bögl Group. realized by bearing pedestals of variable height. Curved sections can be realized depending on radius either by adjustment of the top chord or for small radius by bending the entire beam. The transverse slope of up to 12° can be On request and...

MGB Type III – 9,3 m With its 9,3 m long girder Max Bögl has established an optimized beam for the illustration of the most economical track geometry for at-grade guideways. The system consists of standard beams and inclination as well as pedestal bear- ings are all produced in mass production. This type of girder is implemented without garland shaped prestressing and with π-cross section, that can be realized without a closed end cross section. This leads to further cost-reductions. Concrete-/Steel glide strip In case of settling of the maglev train on its guideway the girder has to...

Air borne sound Because of its material specific characteristics the concrete beam behaves more favorably as hybrid or even steel beams regarding noise emission. The airborne sound emission could be reduced on our all-concrete beams through elimination of the gap between the function level modules, like they are present in hybrid girders. Furthermore the noise can be reduced by external noise insulation elements. Through the choice of the beam’s cross-section form, the sound propagation direction can be controlled, too. steel spring or as PU-material. Through the calculated and chosen...

Concrete bending switch From the engineer’s point of view, the construction and production of a concrete bending switch is a special provocation. The Max Bögl Group has taken on this challenge. 14,4 m long post-tensioned girders are connected to form a switch system, which is bend- ed in transverse direction with rack and pinion drives. The deflection of the switch beams is made possible by constructing slits in the top chord section of the girders. The deformation of the base section is realized with modified concrete, which shows despite its high strength a low E-module. In spring 2009...

Guideway specials Manufacturing of precise track geometry The key to success, particular for the all-concrete beam lies on the one hand in the adjust­ able formwork technology being adopted to standardized girders, and on the other hand in special developed machine technology of Max Bögl, which can process concrete parts in highest precision. This allows and enables a series production of the beams, subsequent fine machining is used to Cable sleeves for transportation Equip with technical, system modules adjust the track geometry and to adhere to the required system’s technical tolerances....
